Corrosion degradation mechanism of phosphate coating and aging time on the anticorrosive properties of phosphate coating on AZ91D magnesium alloy

In order to avoid the blind human activities,it is necessary to deeply analyze and research the degradation mechanism of ecological environment.

Using MR fluids in recoil brake of gun, the damping can be regulated by means of changing consistence of MR fluids to form hydraulic resistance,and law of recoil resistance can also be controled.

Applying principles from hydrodynamics, and considering local losses caused from the complex structures a new hydraulic resistance model for the recoil brake is established An example for this model accords well with the classical theor
